Make the PCB
Find a supplier who produces the PCB from Gerber files. For example in Europe Multi Circuit Boards (MCB) is such a supplier.
Download the Gerber files from here and provide these to the supplier for production. The board size is approximately 55 x 51 mm.
Check the prices carefully because there might be good discounts for larger quantities. For example, at MCB 5 pieces cost exactly the same as one piece. So you might want to get a few more pieces and offer them on Ebay. Or you even check offers there before you place a production order. Producing 5 pieces at MCB costs about 50 € including tax and shipping costs (at time of writing).
There are 2 more files, you probalby don’t need them but I want to keep the package complete:

Soldering
There are no SMD parts on this board so hand soldering works fine, but you need some experience with soldering of course. Just follow these pictures:
Done
You have built your Estlcam Shield. Now let’s see how to use it.
